Popups: With ridiculously high rents, barriers of entry, loads of commercial spaces sitting half empty, and a market of expats who rarely eat in the same place twice in a month, it's the perfect environment to test the market, feed the frenzy and make some quick cash.

What do you do if prohibitive rent prices hold you back from opening a store?  You open a pop-up.  And what do you do when your landlords increase your rent by 250% to HK$7 million per month (US$900k per month) to let the likes of Abercrombie & Fitch in? You open a pop-up that makes a statement.
